絕熱凝結
英文
adiabatic condensation-
With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
研究結果表明：通過對rpc各組分摻量變化的研究，可以找到rpc的最優配合比；試件成型后的熱養護制度對rpc的性能影響巨大； rpc的抗壓應力?應變曲線可以反映出試件受破壞時微裂紋的擴展情況，剛纖維的摻入可以大幅改善rpc的韌性； rpc在成型后存在較大的收縮，而其中的化學收縮要遠遠大於乾燥收縮； rpc具有很強的抗氯離子滲透性能，漿體的密實度很高；通過x射線衍射實驗，可以發現rpc的膠凝體中ch晶體已經幾乎不存在，膠凝體主要由c - s - h凝膠和未水化水泥顆粒組成；在抗溶液侵蝕的實驗中，摻礦渣rpc的抗溶液侵蝕性能在絕大多數情況下要好於不摻礦渣試件，酸、堿溶液和浙江工業大學碩士學位論文摘要一些鹽溶液都會對rpc的結構產生侵蝕作用，但是機理各有不同。The numerical simulation accords with detective values in summing up it may be stated that we must keep the building wall dryness in order to produce a good heat performance, therefore, a air insulation is built in the high temperature layer and a air layer is built to eliminate moisture and exsuction damp in the low temperature layer,
本文指出，為了創造出熱功能優良的建築墻體，必須使建築墻體永遠保持乾燥狀態。因此，為使墻體長期保持良好的絕熱功能，必須在高溫側設置隔汽層，在低溫側設置排濕和吸潮的空氣層並及時排除空氣間層的凝結水及霜。In this paper, referring to qingju water power station, temperature control analysis and study has been done : study on the match ratio of the concrete and question of modifying of the special fine sand concrete to improve resisting ability of splitting of concrete ; study on the technology of the highly mixed fly ash to reduce the adiabatic temperature rise of concrete ; in case of the condition of resisting splitting to allow, study on the temperature control measure to strengthen and water the size of building, simplify the operational procedure, accelerate the construction speed, economize the expenses of the project
